# Exact Alarm and Ring Screen Mechanism

Standard phone notifications are easy to ignore or swipe away when you are
relaxing or procrastinating. Quietube ensures you never miss a planned study
block using Android's high-priority Exact Alarm and full-screen ring
architecture.


THE EXACT ALARM ARCHITECTURE

Quietube uses Android's exact alarm scheduling system:

 * Doze Mode Immunity: Even if your phone has been asleep for hours and entered
   Android battery Doze mode, Quietube's exact alarm wakes up the device on the
   exact designated second.
 * Reboot Resilience: If your phone restarts or runs out of battery, all
   scheduled study alarms and routines are automatically recalculated and
   restored as soon as the device boots up.


THE FULL-SCREEN RING SCREEN

When an alarm triggers, Quietube displays the dedicated full-screen ring
interface:

 * Full-Screen Wakeup: Wakes your display with a clean, focused study bell chime
   and displays your goal for that study block.
 * Two Clear Actions:
   * Start Studying Now: Immediately launches your designated Quiet Session and
     brings up your lecture materials.
   * Snooze (5 Minutes): Delays the reminder briefly if you are wrapping up an
     urgent task, re-triggering the alarm after 5 minutes.
